1st Seattle Escorts – @FansOf1stSeaEsc on Twitter – has been advertising such women as Betty, who likes to dress up as a French maid, nurse or school girl.

Monica is also a rare find, 1st Seattle says. “She is both elegant out on the town and pure enjoyment when you get back to your room,” according to a May 21 tweet.

Rates are advertised as $350 each hour with $175 for an additional half hour, though there are discounts for block rates. The site connected to the Twitter account says to make an appointment, a client should text his name, driver’s license number, the escort wanted, time, place and payment.

“Let’s keep everyone healthy,” the site operator wrote. “What two consenting adults decide to do together is none of my business, but please keep in mind that any Escort who will French kiss you is only as healthy as her last client. Exchanging bodily fluids is bad for everyone. Please don’t ask your escort for special treatment over and above what makes sense.”

The site and its Twitter post aren’t violating any laws, police say.

“There’s nothing that is illegal about advertising for an escort service,” Sgt. Sean Whitcomb said. “However, escort services are sometimes known to be fronts for prostitution services.

“We usually handle this by following up in undercover capacities, which is to say we may be posting as clients and or service providers.

“So the message to the general public is if you use an escort and you’re interested in obtaining sex for cash – you just don’t know if its going to be an undercover police officer or not.”
